Theoretical arguments and simulation results … WebbB bootstrap samples and the find the standard deviation of these means. The more bootstrap replications we use, the more ‘replicable’ the result will be when a different set of samples is used. So if we re-ran the bootstrap analysis, we would be more likely to see the same results if we use a high number of bootstrap samples.
